LINCOLN, Neb. (AP) Glynn Watson Jr. scored a career-high 34 points, Tai Webster made the go-ahead free throw in the last minute of the second overtime, and Nebraska held off Iowa 93-90 on Thursday night.
The Cornhuskers (9-6, 3-0 Big Ten) followed up surprising road wins over Indiana and Maryland with a victory in their conference home opener. They are 3-0 in league play for the first time since 1975-76.
The Huskers had a chance to win in regulation, but Evan Taylor missed two free throws with 1.3 seconds left.
Peter Jok scored 34 points to lead Iowa (9-7, 1-2), which saw its five-game win streak against Nebraska end.
Webster finished with 23 points and seven assists for the Huskers, Jeriah Horne added 12 points and Michael Jacobson had 13 rebounds.
Webster went to the line after Jok fouled out with 54.6 seconds left. He made the first and missed the second, leaving the Huskers with a one-point lead.
Horne made two more free throws with 17.4 seconds to play. The Hawkeyes still had two chances to win, but Jordan Bohannon missed a shot and, after Taylor missed two more free throws, Brady Ellingson was off with his desperation 3-point try at the buzzer.
Nebraska struggled with free-throw shooting in regulation, making just 8 of 19, but needed Taylor to make just one of two to likely win it in regulation.
His first swirled out of the cylinder and the second bounced away. Taylor had gotten his chance after Iowa flubbed its previous possession. Webster stripped the ball from Jok, Horne picked it up for Nebraska and passed ahead to Taylor, who was fouled from behind by Nicholas Baer as he was going to the hoop.
Taylor came into the game having made 12 of 14 free throws for the season but was 0 for 5 against the Hawks.
The Huskers made all six of their free throws in the first overtime to force another period.
Iowa: The Hawkeyes dropped to 0-3 in true road games but hung tough in a hostile environment with a starting lineup that includes four freshmen and a senior.
Nebraska: The Huskers continue to get impressive play from the backcourt of Watson and Webster, who combined for 57 points, and showed their road wins over Indiana and Maryland were no fluke.
Iowa: Hosts Rutgers on Sunday.
Nebraska: Hosts Northwestern on Sunday.
